Eli, the engineer, did a thorough inspection and developed a solid plan for repairs. ESG also offered two levels of fees, which was extremely helpful for my budget. Thank you ESG for the service and peace of mind!"

"I am having a full master bath and kitchen remodel done with new layouts in both rooms and knocking out a wall. Evolution worked with me to quickly get a drawing done of the new layouts so that the contractor could get started on the project. They made sure to include me in the process so that the design would be done exactly as my wife and I envisioned. They communicated effectively throughout the process and were always courteous and professional. I recommend them to anyone with drafting needs."

Structural Engineering questions, answered by experts

Precast concrete can be reinforced with rebar, wire mesh, or other materials to improve its strength and add stability. Precast concrete for large construction projects is often pre-stressed as well for greater structural strength. Reinforced concrete is durable and strong, making it an ideal choice for many construction projects.

It's safe to assume that all exterior walls are load-bearing, or at least have load-bearing characteristics. Some older homes feature porches or bump-outs that don't rest on the home's foundation. However, they still must carry the weight of the roof section they support. Walls containing floor-to-ceiling glass or other non-structural elements must use post and beam configurations to meet load-bearing criteria.

Cathedral ceilings make a statement in your home, but at the cost of your attic space. Normal attics are wide open, which allows warm air to move around and exit your home. Because of this, cathedral ceilings make your home less energy efficient and put your ceiling at risk of venting issues if you’re not careful. They also reduce your attic storage space, potentially cause an echo, and even make it harder to change a light bulb.

The easiest way to tell if a wall is load bearing is to check if it’s an exterior wall or if it runs perpendicular to the joists above and below it (or parallel to beams). Exterior walls are almost always load-bearing, and walls that run under beams or parallel to them are also usually load-bearing. There are exceptions to these rules, and walls that don’t fit into these categories can still be load-bearing. If you’re unsure, hire a structural engineer to look at your home to assess whether or not the wall is structural.

You need to hire a structural engineer when building or modifying any component with a structural load in your home. Common situations where you would need a structural engineer include home inspections when buying or selling a home, investigating possible issues with your foundation, beams, load-bearing walls, or chimneys, breaking ground on a new home or structure on your property, and renovating an old part of your home that could threaten any structural integrity. Home additions and bump-outs also require an engineer.
